ARM: dts: exynos: fix compatible strings for Ethernet USB devices

Fix compatible string for Ethernet USB device as required by USB device schema:
 Documentation/devicetree/bindings/usb/usb-device.yaml
  The textual representation of VID and PID shall be in lower case hexadecimal
  with leading zeroes suppressed.

Since there are no kernel driver matching against this compatibles, I
expect no regressions with this patch. At the same time, without this fix, we
are not be able to validate this device nodes with newly provided DT
schema.
